BOB-SLED.

Specication of Letters Patent.

Application'mea may 1s, 191s. serial No. 98,476.

.bobsleds nd has for its object to provide means fo sled.

Another object of the invention is to provide a sled having horizontal runners diffacilitating the guiding of the ferent-portions of which are on different planes.

Still another object of the invention is to provide a sled having fixed runners different portions of 'which are on diferent planes in combination with a pivotally movable runner whereby the guiding of the sled is facilitated. y

With the above and other objects `in view, I have invented the device illustrated in the accompanying drawings in which--Y Figure 1 is a bottom plan view of my lmproved sled, Fig. 2 is a side elevational view thereof, and Fig. 3 is a front elevational view thereof.

Like reference characters indicate like parts throughout the following specification and in the several views in the drawings in which l'is a sled,` having fixed side runners 2 and 3 the forward portions 4c and 5 of which are on Ya plane slightly above the plane of the rear or main portion 6 and 7 thereof. A pivotally mounted runner-.8 is provided on the forward end ofthe sled which maybe guided through means of the steering bar 9 fixed to the bearing member 10 to which the runner 8 is connected by the standards 11 and 12. The member 10 is pvoted in the recessed transverse bar 13. A`semi-circula'r member 14 provides a side support for the opposite ends of'the steering bar 9. The main portion of the runner 8v is on a common plane with the rear portions 6 and 7 of the runners 2 and 3.' A resilient rod 15 has movable connection with the bracket 16 xed on the rear end of the bearing member 10 and fixed connection with the frame member 17 whereby the member 10, and consequently the runner 8 is held normally parallel with the run.

ners 2 and 3.

Normally the raised ends 4land 5 of the runners 2 and 3 are held above the surface upon which the sled operates, and yet they guard against liability of the sled upsetting from an excess of side weight on front end when` in use. The preponderance of weight is usually on the rear end of the coaster; thus, by the usual straight bearing of the main runners the course of a coaster is not readily deflected; while with my construction, the third runner being short and \having within itself the forward traction power; the steering is easy and prompt, thus avoiding much of the perils of coasting. 19

and 20 are chaing irons against which the member 10 is movable. f

Having now described myv invention that which I claim to be new and desire to procure by. Letters Patent is 1. In a bobsled having a air of runners each of which is stepped, he forward portion beingI on a higher horizontal plane than the rear portion. 2. In a bobsled havingl a pair .of runners each of which isstepped, the forward portion being on a higher horizontal plane than the rear portion and an intermediate pivot.- ed runner. p,

In testimony whereof I affix my signature in the presence of two witnesses.
